30 High Protein Low Calorie Foods for Weight Loss

Why Protein Matters for Weight Loss

Of all the dietary levers you can pull for weight loss, increasing protein is consistently the most effective. Protein is uniquely satiating — it reduces hunger hormones like ghrelin and boosts satiety hormones like peptide YY, meaning you naturally eat less without fighting constant cravings. It also has the highest thermic effect of any macronutrient: your body burns roughly 20–30% of the calories in protein just to digest it, compared to 5–10% for carbs and 0–3% for fat.

Most critically for anyone in a calorie deficit: protein preserves lean muscle mass. When you eat fewer calories than you burn, your body needs to find fuel from somewhere. Without adequate protein, a significant portion of your weight loss comes from muscle rather than fat — leaving you lighter but metabolically weaker. Aim for at least 0.7–1g of protein per pound of body weight (1.6–2.2g per kg) when eating in a deficit.

The challenge is getting enough protein without blowing your calorie budget. That's where high-protein, low-calorie foods become your secret weapon. The 30 foods below are organized by category and ranked by their protein-to-calorie efficiency.

Animal Proteins

Lean animal proteins are the gold standard for high protein density. They contain all essential amino acids in the right ratios and are highly bioavailable — meaning your body actually absorbs and uses almost all the protein they provide.

Chicken breast is the undisputed champion of high-protein, low-calorie eating. At 31g of protein and only 165 calories per 100g cooked, it delivers nearly 75% of its calories from protein. Egg whites are even more remarkable at just 52 calories per 100g — perfect for adding bulk to omelettes without adding significant fat. Whole eggs are also excellent: the yolk contains fat-soluble vitamins, choline, and healthy fats that make them far more nutritious than whites alone.

Seafood & Fish

Fish and shellfish are among the most protein-dense foods on earth, and most are extremely low in calories. They also provide omega-3 fatty acids, iodine, and selenium — nutrients that support thyroid function and metabolism.

Shrimp and crab are calorie-bargains — under 100 calories for 100g with nearly 20–24g of protein. Canned tuna in water is one of the most practical high-protein foods because it requires zero cooking, travels well, and costs very little. Salmon is slightly higher in calories due to its healthy fat content, but those omega-3s make it worth including 2–3 times per week.

Dairy & Dairy-Based Proteins

Dairy proteins — particularly casein and whey — are exceptional for muscle preservation. Casein digests slowly, making dairy ideal before bed or between meals to provide a sustained amino acid release.

Non-fat Greek yogurt and low-fat cottage cheese are the MVPs of dairy protein. Cottage cheese in particular is massively underrated — a cup delivers 28g of protein for just 163 calories, and it's mostly casein, making it ideal as a slow-digesting nighttime snack. Skyr (Icelandic-style yogurt) is even thicker and higher in protein than regular Greek yogurt, with a similar calorie count.

Legumes & Plant-Based Proteins

For vegetarians, vegans, or anyone looking to diversify protein sources, legumes offer an impressive amount of protein along with fiber, complex carbohydrates, and micronutrients. While they're not as bioavailable as animal proteins, combining them with other plant proteins throughout the day covers all essential amino acids.

Seitan (wheat gluten) is the highest-protein plant food by weight, rivaling chicken breast at 21g per 100g. Edamame is one of the few complete plant proteins — it contains all nine essential amino acids. Tempeh edges out tofu in protein and has a firmer texture, making it excellent for stir-fries and salads.

High-Protein Vegetables & Other Foods

A few vegetables and other foods punch above their weight in protein — useful for bumping up your daily total without a dedicated protein source at every meal.

• Peas (1 cup cooked) — 134 cal, 9g protein
• Broccoli (1 cup cooked) — 55 cal, 3.7g protein
• Edamame in pods (1 cup) — 94 cal, 8.5g protein
• Spirulina (1 tbsp / 7g) — 20 cal, 4g protein
• Hemp seeds (3 tbsp / 30g) — 166 cal, 10g protein
• Pumpkin seeds (30g) — 163 cal, 8.5g protein

How to Add These Foods to Your Meals

Breakfast

Start the day with protein to stabilize blood sugar and reduce mid-morning hunger. Try scrambled egg whites with a whole egg, a Greek yogurt or skyr parfait with berries, or cottage cheese blended into a smoothie (it adds 20+ grams of protein without changing the flavor noticeably).

Lunch

A large salad with canned tuna, shrimp, or grilled chicken breast provides 30–40g of protein for around 300–400 calories. Lentil soup (a full can or homemade) is an excellent plant-based option at 18g protein per cup. Edamame makes an easy high-protein side.

Dinner

Build your dinner plate around a lean protein centerpiece — a baked cod fillet, turkey tenderloin, or firm tofu stir-fry. Fill half the plate with non-starchy vegetables and a quarter with a complex carb. This structure naturally creates a high-protein, moderate-calorie meal.

Snacks

High-protein snacks prevent the energy crashes and overeating that often derail calorie budgets. Good options: a hard-boiled egg (6g protein, 78 cal), a container of low-fat cottage cheese (14g, 81 cal), or a whey protein shake (24g, ~120 cal). Pair with fruit or vegetables to add volume and fiber.

Tracking Protein Accurately

Protein targets are impossible to hit consistently if you're not tracking them. MyBiteIQ logs protein, carbs, fat, and calories automatically from a photo of your meal — so you can see at a glance whether you're hitting your daily protein goal without manually logging every ingredient.
